bah, it's working again after restarting the compositor
Can you obtain a stack trace?
Yeah, it is crashing again.
I'm no expert with meson nor with gdb, but here you are:

The following line of the backtrace suggests that the
pixman_image_t * common_imageis being set to NULL at render.c#L134. This might be caused by grim receiving incorrect parameters about the outputs from hyprland. Could you please report the Wayland debug log output? (i.e, runWAYLAND_DEBUG=1 grim, and provide the logs that are printed.)

Sorry, I should have been more precise: could you please post the
WAYLAND_DEBUG=1 grimlogs from an unsuccessful run, where grim segfaults? {I am assuming grim did not crash here, since the last lines of the log shows cleanup requests, likezxdg_output_manager_v1@6.destroy(), that only run after grim has saved an image.)Alternatively, inside
gdb, runbt fullto get a stack trace that (assuming a debug build) prints the state of all variables on the stack.
Yes it is working again.
I'll post it if and when it segfaults again.

zxdg_output_v1@3.logical_position(-1337420, -1337420)
This explains the crash. If I understand the code correctly, grim tries to render onto an image which contains both HDMI-A-1 and eDP-1 at the logical positions specified. Since the compositor claims that HDMI-A-1 is very far to the the left, and very far up, the smallest rectangle containing the two has size
1337420+1920 = 1339340by1338500, and any image of that size requires much more memory to store than is available; thus creatingcommon_imagefails, and grim crashes later on.
so we should ...... ?
We should probably exit with a clear error instead of segfaulting.
and in order to don't have the error and take the screenshot we should .... ?
We shouldn't support this case, no. You need to reconfigure your outputs to have a more reasonable layout.
I configured my external monitor HDMI-A-1 to mirror my laptop monitor, and in fact Hyprland only reports 1 monitor:
❯ hyprctl monitors Monitor eDP-1 (ID 0): 1920x1080@144.149002 at 0x0 description: AU Optronics 0xAF90 (eDP-1) make: AU Optronics model: 0xAF90 serial: active workspace: 3 (3) reserved: 0 30 0 0 scale: 1.00 transform: 0 focused: yes dpmsStatus: 1Can you tell me how you figured out there was an external monitor too?
This is the relevant config in my hyprland.conf file:
# MONITORS # See https://wiki.hyprland.org/Configuring/Monitors/ monitor=eDP-1,preferred,auto,1 monitor=HDMI-A-1,preferred,auto,1,mirror,eDP-1
The compositor advertises it via the Wayland protocol.
wayland-infoshould show it too.
So I paste the following and the link to this issue in the hyprland issue report?
interface: 'zxdg_output_manager_v1', version: 3, name: 21 xdg_output_v1 output: 47 name: 'HDMI-A-1' description: 'Samsung Electric Company C24F390 H4LT305839 (HDMI-A-1)' logical_x: -1337420, logical_y: -1337420 logical_width: 1920, logical_height: 1080 xdg_output_v1 output: 45 name: 'eDP-1' description: 'AU Optronics 0xAF90 (eDP-1)' logical_x: 0, logical_y: 0 logical_width: 1920, logical_height: 1080
Yes, please report this as a bug to the hyprland devs.
I don't think you should try to capture both monitors if the external one is a mirror?
Why you don't capture just one of them?
We have no way to detect that one is a mirror of the other.
But when it works, because most of the time it works, I only capture one monitor.
I don't capture an image file with two monitors side-by-side that display the same thing.
I don't understand how that is possible, if we always captured both of them?
If both monitor's positions overlap, grim will overwrite one monitor's content with the other.
If both monitor's position and size are exactly the same, grim might be able to detect and avoid copies. But that's not the case in the log you gave above.
So you are telling me that when it works, the two monitors have the same logical position and logical size?
So now Hyprland decided it was proper to change the logical position of one of them for some reason?
I don't know. Would need some
WAYLAND_DEBUG=1logs collected when it works to tell.
Here it works:
